another possibility on Mac is syphon Recorder. I use it always, it is easier to configure as OBS and it works very well:

try the OBS

 This is definitely the way to do it.

@video-architect Hello! I hope the included screenshot helps. I was running a workshop and wanted to demonstrate how LED lighting units can be controlled by Isadora + TouchOSC on an iPhone to provide realtime control of the color palette. I used an Enttec Din Ethergate 2 ethernet to DMX convertor.

Best wishes,

Simon

Have you seen these tutorials?

Re: [DMX and Isadora](/topic/3237/dmx-and-isadora)

Hi, 

I'm having some difficulties finding documentation or how to resources for integrating DMX into an Isadora project. 

I have found some actors at the "ADD ONS" page. And I also found a forum post by Gunther from 2017 that had some info but some of the links seem to have expired.

So Im wondering.... 

if there are any other more up-to-date resources around that would be a good place to start from? and

What actors on the add on page would be good to start with. [I did find an actor on Github "ENTTEC-DMX-USB_lightcontrol.izz" that looks simple but I get nervous about downloading things from git-hub.]

All I am wanting to do is throw some symapathetic/complimentary lighting into a courtyard where I have a fairly simple projection of coloured objects. Perhaps responding to the different hues of the coloured objects perhaps. I think have access to an Enttec ODE MkII and Chauvet DJ D-fi(?) Hub unit for testing/development. I've seen Enttec mentioned in a few posts about izzy.

Currently on izzy 3 and financially challenged.

cheers

Ok, Ill try it in the break,

Capturing on ssd nearly killed it... 

Thank you

- Turn on Syphon in Isadora in stage set up

In OBS, on the bottom left, there is the box for sources.

Click on the + button to bring up the source option

You should see Syphon in the pop up menu.

When you select Syphon, then you need to set the source e.g. Isadora Stage 1.

Your syphon feed should appear in the left hand preview window. Use CUT or the slider to bring the preview into the output pane.

You might need to check the Settings (Bottom RIght tab) for the quality of the recording.

Click on Record. It will default to the movie folder.

Best of luck with it.

Oh I realised something from that,

I put it as a QuickTime movie, that makes the file 15 gb for just 5 min. 

Ill try also record to an ssd... for now since I need to figure out the obs and first show is in half an hour:)

Thanks

With 55gb left, you might get a warning that you are low on space if your drive is a Terabyte, since this would put you below 5% drive space pretty quickly.

Assuming you are using the MP4 / H264 Record Stage Setup - Codec:

🎥 Typical 1080p H.264 Bitrates

The Data Rate can be set in the Record Stage Setup dialog, via the 'Max Data Rate' selector. 
You really shouldn't need to use anything higher than 12 Mbps.

Here are some specs on recording transfer sppeds:

🎥 Typical 1080p 30fps H.264 Bitrates

Your external USB drive (assuming SSD) is likely fast enough for the job.
I use Black Magic Designs Disk Speed Test to verify my drive speeds for such things.
It is included in the FREE Black Magic Desktop Video software:  Blackmagic Design Downloads

It sounds like you have a lot of items on your HD. 1hr of HD video is about 10GB and your buffer is probably getting overloaded etc.

If you can free up some space, you might have more chance of getting a record but nonetheless, try the OBS/wirecast route and hopefully it will record a better copy without stressing your remaining space.
